Fig. 2 represent a Vertical section through the same. Fig. 3 represents the wire socket detached.

The nature of my invention consists in making the socket ot' the artificial limb and the cylinder which sustains the same of galvanized-wire cloth.

I construct my artificial limb A from any of the known materials and in any ofthe known I forms. rIhereto I annex a socket, B, and the cylinder O, which sustains the socket, of galvanized-wire cloth, of iron, steel, copper, Zinc, or other metal or material.

The operation is to combine lightness with durability, and secure health to the stump by affording to it' freevcntilation, obviate friction and its consequences, while the limb may be worn without pain or other inconvenience to the patient which belong,` to sockets and cylinders made of wood, leather, gutta-percha, or other material in use for this purpose.
